Dr. Matt Jordan, performance scientist at the University of Calgary, joins Alex to explain why muscle power — not strength — is the single biggest predictor of whether you'll live independently into your 80s. He breaks down what it is, why you're already losing it, and exactly how to train it.
Muscle power is the strongest predictor of how well you'll age, and most people have never trained for it. In this episode of Cascaid Effect, host Alex Galeazzi sits down with Dr. Matt Jordan, performance scientist and researcher at the University of Calgary, to explain why muscle power, not muscle strength, determines whether you'll live independently into your 80s.
Muscle power is strength and speed combined, and it starts declining in your 30s and 40s at a rate of one to two percent per year. The clinical term is dynapenia, and it's the longevity metric almost nobody is measuring. Dr. Jordan has spent more than 20 years working with Olympic and professional athletes, and what he's learned about power training applies directly to healthy aging, fall prevention, and functional independence.
In this conversation on muscle health and longevity, they cover the difference between muscle strength and muscle power, why resistance training matters more for aging adults than for young athletes, the four roles of muscle in human movement, and the frailty cascade that leads from power loss to falls, social isolation, and loss of independence.
Dr. Jordan also breaks down exactly how to train muscle power, including the practical protocol of using 30 percent of your one rep max and moving it as fast as possible, why you should stop the set when bar speed drops rather than training to failure, and why hiring a coach outperforms any supplement you could buy.
Topics include muscle power, dynapenia, sarcopenia, resistance training for longevity, healthspan, functional independence, fall prevention, power training protocols, and mechanical biomarkers.
If you've ever thought resistance training was just for athletes or people chasing aesthetics, this episode will change how you think about aging.
